Posted by Dave Enoch On May - 02 - 2009

Would'nt that be amazing to be invisible. The scientists have kept a step forward and made a cloak which is called an invisibility cloak which neither absorbs nor reflects light making the body invisible. This can lead to invisible suits which are going to be available in the market but may be expensive at the start.

Scientists finally fabricate the first plasma transistor.Though this is not good enough to be used in the commercial systems but this has made a path to use them in future.
In the plasma transistor, the electron emitter injects electrons in a controlled manner into the sheath of a partially ionized neon gas (the plasma). The scientists discovered that even a voltage as low as 5 volts can change the properties of the microplasma, including quadrupling the current and increasing the visible light emission.

The storage capacity of micro-holographic discs that the normal DVDs or the blue-ray discs because the micro-holographic discs store information in a 3D way rather than just putting it onto the surface of the disc.
G.E(General Electrics) has made dramatic changes in the material to increase the reflectivity of the surface.If the reflectivity of the surface increases then the amount of information that can stored automatically increases.

If you were to soak even your best raincoat underwater for two months it would be wet through at the end of the experience. But a new waterproof material developed by Swiss chemists would be as dry as the day it went in.
Lead researcher Stefan Seeger at the University of Zurich says the fabric, made from polyester fibres coated with millions of tiny silicone filaments, is the most water-repellent clothing-appropriate material ever created.

INDIA TACKLES CYBER CRIME

Posted by gamer On 12:30 AM
India's top police officials and information technology experts are meeting in Delhi to discuss ways of countering cyber crime.
The one-day "Cyber law and police" seminar has been organised by India's leading crime-fighting agency, the Central Bureau of Investigation (CBI).
Information and Technology Minister, Pramod Mahajan told the gathering that computer crime would soon be the biggest challenge for the police and lawmakers.
Mr Mahajan said the authorities need to wake up now, or face becoming mere spectators as criminal IT use increases.
Computer crimes mainly involve unauthorised access, data alteration and destruction and theft of intellectual property.
"Crimes like fraud, pornography, illegal sales can all be done by computers," Mr Mahajan said.
He also warned that cyber crimes could take on a far more serious dimension in the near future.
New breed Experts believe a new breed of criminals could damage telecommunications or rail links, disrupt power supplies and harm other important parts of India's infrastructure.
The CBI has invited senior police officials from across India, and IT and law experts to work out effective ways of fighting cyber offences.
The CBI chief, R K Raghavan, said they had sought help from several foreign agencies, including the US Federal Bureau of Investigation, in tackling the recent boom in cyber crimes.
Last year, FBI experts visited India and trained policemen in dealing with such offences. The CBI has now set up its own special cyber crime unit.
The Indian parliament recently passed a law dealing with computer crimes, but experts say police and security agencies need to be more pro-active in dealing with the growing threat.
